The Earth.
Once a peaceful,beautiful and harmonious planet for life — has become a world swallowed by endless wars and disasters.
However,the world didn't end like this simply by human hands — rather,it was the work of the ruthless,cold,merciless aliens who gave no warnings,no mercy and sought only domination.
The aliens came as two.
The Barbaricus,that proudly show off their strength that was built for destruction.
The Ingeniousus,with minds sharper than any blades.
